Unable to activate Fences. Error code: -205

Unable to activate Fences. Error code: -205

I've tested the activation in two different computers (both with a name without symbols) and it failed in both of them. I have also tried to register the key in my account and an error is displayed: "The serial entered is not valid."

Offline activation produces the following error when req file is uploaded:

"An error occurred while updating the entries. See the inner exception for details. (1001)"
